Turns out that indeed may be true as someone dug up a video interview with Trevorrow from back in June where Trevorrow seems to suggest his next project is Star Wars -- albeit without directing stating so.

I can’t speak with any specificity as to what the next thing will be. There are amazing opportunities that have arisen as a result of this. One of them, I will say, will probably create a good deal of ire against me on the Internet when people find out what it is. So, I just want to say in advance that I promise you, for all those who love the mythology that I will be tackling, trust that I love it as much as you do. And I will respect it, and hopefully make it not suck.
